TYPEWRITING MACHINE.

Application filed May 4,

To all whom it my concern:

Be it known that I, ALFRED G. F. KUROW- SKI, a citizen of the United States, residing in Brooklyn Borough, in the county of Kings, city and State of New York, have invented certain new and useful Improvements in TypewritingMachines, of which the following is a specification.

This invention relates to typewriting machines, and is herein disclosed as applied to a machine embod ing many of the featuresshown in my app ication Serial No. 170,354, filed May 23, 191 7(now Iatent No. 1,356,926, dated October 26, 1920), in which the typewriter carriage is provided with a set of decimal-tabulating sto s and a set of column-selecting stops, eit er of which is adapted to co-operate with key-operated carriagearresting counter-stop devices.

In said patent, there is shown a single set of tabulating-keys which is adapted to operate either of two sets of counter-stop devices, according to the character of work in hand. The set of sto s shown in said patent for use in decimal tab table stop at every letter-space of the typewriter carriage, said stops being adapted to be selectively set by a stop-setting key. The other set of stops shown therein comprises variously formed extensions to enable the stops to selectively be efl'ective to arrest the carriage according to the tabulating key depressed at the moment.

According to the present invention, these latter stops may be identical in form, but may be ada ted to be variably positioned to be selective y eifective in arresting the carriage. These latter stops, according to the present invention, may be selectivel and variably set by a stop-setting key, and, if desired, there may be one of such stops for every letter-space in the travel of the typewriter carriage. I

To cause the typist to feel that the stops are being properly set, the setting key may have a uniform throw, and a finger-piece may be provided which varies the amount of throw of the device which is utilized in the setting of any stop, thereby enabling the key to variably set said stop according to the setting of the finger-piece. This structure enables a typewriting machine to be provided with a decimal-stop-setting keyand a column-stop-setting key, thus making a machine of which the method of operation ulating includes a set- 1920. Serial No. 37am.

appeals to the average typist, whose mind is accustomed to deal with keys rather than stops and rack-bars.

Other features and advantages willherestop-setting mechanism before the stop-setting key is depressed, but with the fingerpiece adjusted to set a column-stop for the first column.

Figure 5 is a similar view, but showing the key depressed and in the act of setting the stop.

Figure 6' is a view similar to Figure '5, but showing the stop-setting mechanism setting a stop adapted to arrest the carriage at the last column. In the Underwood typewriting machine, character-keys 1 depress key-levers 3 to rock bell-cranks 4, to swing type-bars 5 upwardly and rearwardly against the front side of a platen 6 mounted to rotate in a carriage 7. The carriage is controlled at the actuation of the keys 1 to travel step by step in a letterfeeding direction by an escapement mechanism, which includes a rack 9 hinged on the carriage 7 and engaging a pinion 10, which, in turn, is controlled in its rotation by an, escapementwheel 11. The escapementwheel 11 is permitted to have an intermittent rotation by means of a pair of fast and loose dogs 12, rocked at the actuation of each key by means of a universal frame 13, in turn, rocked by engagement therewith of a heel 14 carried by each of the type-bars 5.

In addition to having step-by-step movements, the carriage 7 may be jumped a' number of letter-spaces or decimal columns at a time, to any desired zone or major column.

in its movement to any one of thesuceeding zones or columns, omitting or passing by one or more of the intermediate zones or major columns. In either case, the jump move-' ments of the carriage may be controlled by the same set of tabulating keys 15. The keys 15, when depressed, rock key-levers 16 which are pivotally mounted intermediate their ends on a commonpivot-rod 17 The key-levers 16 have associated therewith two groups of bars or plungers, slidably mounted in the main frame of the machine, one

lunger in each group for each key-lever.

ne set of these plungers 18 forms a decimaltabulating group of counter-stops for selecting particular decimal columns or letterspaces in major columns or zones. The bars or plungers 19 of the other set are adapted to select any one of a series of' columns or zones within the capacity of the carriage, so that the carriage maybe jumped from a starting position to any subsequent desired major zone or column, skipping, if necessary,

intermediate columns or zones.

To enable the-tabulating-keys 15 to selectively operate either set of plungers 18 or 19, there are provided a series of interponentlevers 20, having heads 21, which are adapted to be interposed between the tabulating key-levers, and either the plungers 18 or the plungers 19. The interponents 20 are floatingly mounted, by being pivoted on a rod 22. which is supported by a shiftable frame 23. The shifta-ble frame'23 can occupy either of two positions, being thereby adapted to actuate the plungers 18 or the plungers 19 at the depression of the keys 15.

To adjust the shiftable frame 23 there is provided a decimal-tabulating shift-key 24 and a column-selecting shift-key 25. These keys are mounted, respectively, on thrustrods 26 and 27, pivotally connected at their rear ends to rock-arms 28 and 29 upon a shaft 30. The arm 29 is connected by a link 31 to the rod 22 of the shifting-frame 23, said link having a projection 32, lying in front of, and adapted to engage the shiftframe 23. The two positions of the shift frame 23, and thus of the interponents 20, are determined b any desired device, one suitable device being described in my patent aforesaid.

To enable the plungers 18 or 19 to arrest the carriage in any position, the plungers are adapted to release the carriage from the escapement-wheel 11, to enable the carriage to travel under the influence of its springbarrel 33 until arrested in a manner which will be later described. To effect this, the plungers 18 and 19 are provided with heels 43, a l of which are adapted to engage a single universal bar 44, forming art of a rock-frame 45, pivoted at 46; hen any plunger rises, the universal bar 44 is forced upwardly, and rocks a forwardly-extending 57 provided on their edges.

maaeoe arm 47 with the result that the arm 47 draws down on a link 48 to rock a lever 49, carrying at its front end a roller 50, which underlies the rack 9, and thus raises the rack out of engagement with the pinion 10. Thus, when any one of the tabulatingkeys 15 is actuated to actuate either of its plungers 18 or 19, the carriage is free to move until arrested by either decimal-stops 51 or column-stops 52, according to the tabulating connections efi'ective at the moment. With the interponents 20 in the Figure 1 position, underneath the decimal-tabulating plungers 18. the depression of a tabulating key 15 raises its decimal-plunger 18, against the tension of its spring 53, into the path of such decimal-stops 51, as may be set.

There is a series of these decimal-stops 51, herein shown as comprising one for each letter-space or decimal position of the carriage 7. They are adjustably mounted on the carriage 7 in a rack-bar 54 to occupy either an ineffective raised position or an effective depressed position. The decimal-stops 51 lie in vertical slots in the rack-bar 54, and have projections 55 limiting their upper and lower positions. They are adapted to be detained in their different positions by spring-pressed ball-detents 56 adapted to engage in notches hese stops are adapted to be set by a key-operated stopsetting arm 63 (Figure 2) in a manner set forth in some detail in my said patent, the connections being such that when the carriage is positioned at any letter-space, the operation of the key which controls the stop-setting arm 63 sets the corresponding stop, so that when a decimal-plunger or counter-stop 18 is operated, and the carriage is released thereby, the carriage will travel until the set stop 51 is intercepted by the raised plunger or counter-stop 18 and arrests the carriage. In performing this 0 eration, of course the decimal-selecting shi tkey 24 must be at its rearward position, as shown in Figures 1 and 2, for holding the interponent-levers 20 at their forward positions with their heads 21 beneath the lower ends of the decimal-tabulating plungers 18. as shown in Figure 1. 7

Since there are usually ten of the tabulat-. ing keys 15, there are usually ten of the plungers 18, and the carriage isadapted to be arrested through the set stop 51 at-any decimal place in a column ten etter-spaces wide, the space at which it is arrested depgnding on the actuated key 15. There may provided an unsetting slide 64 of any usual or desired form, adapted to reset all the set stops 51, to enable suitable 'stops to be set up for any work in hand.

When it is desired to position the carriage selectively at an one of a plurality of columns by the co umn-stops 52, the columnshifting-key 25'is actuated to carry the in terponents 20 rearwardly to the position shown in dotted lines at Figure 1 with their heads 21 under the columnselecting plungers 19. Actuation of any one of the tabulating keys 15 at this time lifts the associated plunger 19 to release the carriage by actuating the universal bar 44, so that the carriage travels freely until a set column-stop 52, like the one seen in the foreground in Figure 5, intercepts a feeler or trip 66, which has been raised by the actuation of the plunger 19 at the de pression of the key 15.- There is a series of the column-stops 52, and there may be one of these stops for each letter-space position of the carria e 7, as shown in Figure 2. This provides or choosing or selecting ten col- ,umn-stops 52 to correspond successively with the respective ten tabulating keys 15 in such manner that the successive columns of a work-sheet may be variably spaced as desired, according to the particular kind of work in hand. The catch or feeler 66 is in itself ineffective to arrest the carriage, but, when struck by a lug 67 on the column-stop 52, the feeler is pushed to the left at Figure 3, thus rocking leftwardly a rock-frame 67, pivoted on a part of the main frame of the machine and upon which the feelers 66 are pivoted, said frame 67 comprising a finger 68 which hes in an opening 69 in a counter-stop 70, the connections being such that the rocking of the frame 67 lifts the counter-stop 70 into the path of the stop 52, as shown in F igure 5, with the result that the counter-stop intercepts the stop 52 and arrests the carriage. In this connection, it should be noted that Figure 5 diagrammatically represents not only the setting of the stop 52, but also represents diagrammatically the arresting of the carriage by the stop 52, operations which ordinarily would not take place at the sametime. v

To effect the lifting of thecatch 66 to position where it is intercepted by the lug 67, in the manner described, the plungers 19 are provided with the connections described in some detail in said patent, said connections including a set of nested arms 71, which extend from the plungers and are bent at right angles, to enter forked ends 70 in the trips 66. Each arm 71 is successively longer than the adjacent one, and is adapted to operate the stopcatch 66 next further away, to correspond with the successive columns from one to ten. To enable the unset stops 52 to pass freely by the set counter-stop 70 while the set stops 52 selectively co-operate with the various catches or trips 66, each stop 52 is cut away at 72, betweenthe body of the stop and the lug 67. When ten of the columnstops 52 are set, each lug 67 will co-operate only with its own catch or trip 66.

To enable any stop 52 to be set to co-operate with any trip 66, there is provided a stopsetting member or arm 73, lying behind the path of the stops 52 and adapted to be moved forward by a stop-setting key 74 to variably position the stops 52. The stop-setting arm or bar 73'is pivoted at 75 on a bracket 76 near the bottom of the machine, to enable the are through which the arm 73 swings substantially horizontally to be of wide curvature. To hold the arm 73 in position to co-operate with only a single stop 52, it is provided with an enlargement 77, having an elongated'slot 78 through which a shouldered screw 79 passes and is threaded into a bracket 80 fast on the frame 81, inwhich the tabulating plungers 18 and 19 are mounted.

. The connections between the key 74 and the arm 73 include a link 82 pivotally attached at 83 to the arm 73, and pivotally attached at its front end to a rock-arm 84 fast to a transverse rock-shaft 85 extending to the side of the machine, said shaft being adapted to be rocked by the depression of the key 74. The'link 82 is provided with a suitable arcuate portion 86 to enable it to swing clear of the escapement devices and other mechanism.

To draw forward the link 82 to set a stop 52, the key 74 is on a lever 74, pivoted at 87 on a bracket 88, so that an upstanding end or arm 89 of the key-lever swings forwardly against a substantially vertical transverse extension 90 of a link 91, which is pivotally connected to a rock-arm 92, fast to the rock-\ shaft 85, on which the rock-arm 84 is also fast. Thus, depression of the key 74 draws forward the links 91 and 82 and sets the stop 52. To enable the key 74 to have a uniform throw, and yet variably or differentially set a stop 52, according to the column to which it belongs, there is provided, on the frame 81, an abutment-forming stop-pin 93 adapted to arrest the key-lever at the downward limit of its throw, and the link 91 is given a variable throw, because its extension 90 normally stands at a variable distance from the end 89 of the key-lever, being formed on an arc having a center near the shaft 85.

In order to vary the lost motion between the extension 90 and the extension 89, there is provided a finger-piece 94 pivoted upon a bracket 95 on the outside of the t pewriting machine frame, said finger-piece fbrming the upper end of a bell-crank 96, having a rearwardly-extending arm 97, which carries a roller 98 riding in a slot 99 in the front end of the link 91, with the result that when the finger-piece 94 is drawn forward along its guide 100, it lifts the extension 90 from the Figure 1 to the F igure' 4 position, through the intermediate positions. In the Figure 1 position, there is substantially no lost motion between the extension 90 and the lug or roll 101 by which the end 89 operates it. In the Figure 1 position, therefore, the depression of the key 74 to its full extent moves the setting arm 73 to its full extent and moves the stop 52, with which the arm 7 3 engages, from its Figure 1 position to its Figure 6 position, that is, to its fullest extent for arresting the carriage at the last column. In the Figure 1 position, the fingerpiece 94 is drawn forward to its foremost or number 1 position along the guide or rack 100, with the result that the depression of the key 74 is idle for the greater part of its stroke, and only actuates the setting arm 7 3 far enough to shift a stop 52 from its Figure 1 to its Figure 5 position, for arresting the carriage at the first column.

To prevent any tendency to slip, the surface of the extension 90, where engaged by the lug or roll 101, is provided with teeth 102, spaced to correspond with the notches 1 to 10 of the rack 100. Each stop 52 is provided with corresponding depressions 103, which are adapted to be engaged by a spring pressed ball-detent 104 to hold the stop in its set position, corresponding to the action of the lug or roll 101.

In order to provide a comparatively wide arresting surface for the stop 52, the movement of the stop from its ineffective position, shown in Figure 1, to its first effective position, shown in Figure 5, is greater than its subsequent movements, thus making it practically impossible for the counter-stop 70 to catch that stop on the corner and injure it, arresting the heavy carriage.

To return the stops 52, there is provided a suitable returning-bar 105, lying in front of all the stops 52, and supported at each end upon a sliding bracket 106, so that the two ends can be moved simultaneously by a shaft 107, having a pinion 108 at each end lying within an opening 109, of the adjacent bracket 106, each opening having a rack 110, adapted to be engaged by the pinion 108. To rotate the shaft 107, there may be provided a handle 111. To return the key 7 1 after its actuation, there may be provided a spring 112, anchored in the bracket 88 on which the key is pivoted; and to independently return the setting arm 73, there may be provided a spring 113, fast to the link 91, and anchored in any siutable position.

In order to keep the returning-bar 105 normally in its ineffective provided a spring 114 anchored to said bar and to a suitable bracket, tending to draw said bar forwardly. The rack-bar in which the stops 52 are mounted on the carriage 7 is in the form of a pair of facing-racks 115 and 116, in the upper one of which. 115, are mounted the ball-detents 104. The lower rack-bar 116 is constructed, in any suitable manner, with a central opening 117. in order to leave a clear space through which the counter-stop 7 O can rise when it is actuated. To support the upper end of the counterstop against being bent by the carriage,

position, there is r when actuated, there is provided a pair of lugs 118, rising above the cap 119, of the casing, in which the counter-stop works.

The key 7 4 works in the usual key-lever comb 120, and is provided with a lug 121, adapted to strike the comb 120, and limit its return by the spring 112. The finger-piece 94 is mounted outside the frame of the typewriter, and its rearward extension 97 is also outside the typewriter frame, and is connected to the roller or lug 98, which works in the fork. or slot 99, by a horizontal crosspiece 122, which extends within the typewriter frame, and then is bent downwardly at 123 to carry the roller or lug 98.

Variations may be resorted to within the scope of the invention, and portions of the im rovements may be used without others.
